Characterised control valves (CCV) with adjustable flow rate,
sensor-operated flow control and monitoring
P6..W..EV-BAC
Product features
Principle of operation
Flow rate curves
The actuator is comprised of four components: characterised control valve (CCV), measuring
pipe with medium velocity sensor, temperature sensors and the actuator itself. First of all, the
maximum flow rate (max) is set on the actuator, whereby max is permitted to represent 45%
to 100% of the greatest possible flow rate nom. At the same time, the max value is assigned
to the maximum positioning signal (typically 10 V). Because of the fact that the characterised
control valve (CCV) exhibits an equal percentage valve characteristic curve, the positioning
signal for the flow rate is also depicted in equal percentages, i.e. 70% of the positioning signal
corresponds to 38% of the max value.
The actuator control can be either communicative or analogue. The medium flows in the
measuring pipe with a velocity of up to 2 m/s, is detected by the sensor and is applied as the
flow value. The measured value is compared with the setpoint. Depending on the deviation, the
actuator moves the ball of the characterised control valve (CCV) into the required position and
acts as a throttling device. The angle of rotation α varies according to the differential pressure
through the final controlling element (see volumetric flow curves).

The angle of rotation (α) will differ, depending
on the differential pressure (∆p) and
the volumetric flow required (),
The actuator is equipped with two temperature sensors. One sensor (T2) is integrated in the
measuring pipe, the second sensor (T1) is enclosed with the system, already wired, and must
be installed in the water circulation at the site. The sensors are used to record the medium
temperatures of the supply and return lines of the consumer (heat/cold register). As the water
quantity is also known thanks to the volumetric flow measurement integrated in the system, the
power released from the consumer can be calculated. Furthermore, the heating/cooling energy
is also determined automatically by means of the evaluation of the power over time.
The current data, e.g. temperatures, volumetric flow volumes, exchanger energy consumption,
etc. can be recorded and accessed at any time by means of web browsers or communication
(BACnet or MP bus).
The recorded data (integrated data recording for 13 months) can be used for the optimisation of
the overall system and for the determination of the performance of the consumer.
Download csv files through web browser.
Manual override with push-button possible (the gear is disengaged for as long as the key is
pressed or remains locked).
The actuator is overload-protected, requires no limit switches and automatically stops when the
end stop is reached.
The actuator moves to the home position when the supply voltage is switched on for the first
time, i.e. at the time of commissioning or after pressing the «gear disengagement» key,
The actuator then moves into the position defined by the positioning signal.
The parameterisation can be carried out simply and rapidly through the integrated web server.
The actuator can be installed standing to lying.
The characterised control valve may not be installed in a
hanging position i.e. with the spindle pointing downwards.

Installation instructions
Water quality requirements
• The water quality requirements specified in VDI 2035 must be adhered to.
• Ball valves are sensitive regulating devices. The use of dirt filters is recommended in order to
prolong their service life as modulating instruments.
Maintenance
• Ball valves, rotary actuators and sensors are maintenance-free.
• Before any kind of service work is carried out, it is essential to isolate the rotary actuator from
the power supply (by disconnecting the power lead). Any pumps in the part of the piping system
concerned must also be switched off and the appropriate slide valves closed (allow everything
to cool down first if necessary and reduce the system pressure to ambient pressure level).
• The system must not undergo recommissioning until the ball valve and the rotary actuator
have been properly reassembled according to the instructions and the pipeline has been
refilled in the proper manner.
Direction of flow
Installation in the return
Inlet section
The direction of flow, specified by an arrow on the housing, is to be complied with, since
otherwise the flow rate will be measured incorrectly.
As a general rule, the device is to be installed in the return.
In order to achieve the specified measuring accuracy, a flow-calming section or inflow section
in the direction of the flow is to be provided upstream from the measuring pipe flange. Its
dimensions should be at least 5 x DN.

Valve design
/8
It is imperative that the measuring pipe be
correctly earthed in order to ensure that the
medium velocity sensor does not make any
unnecessary incorrect measurements.
If no hydraulic data are available, then the same valve DN can be selected as the heat
exchanger connection DN.
If the valve is assigned to the last consumer, then the pressure drop in the measuring pipe is
30 kPa with nom. If the flow rate is 50% of the nom, then the pressure drop for the length of the
measuring pipe will be only ¼ and equals around 8 kPa. (The measuring pipe/valve pressure
drop ratio is 58:42)

Installation of immersion sleeve and
temperature sensor
The valve is equipped with two temperature sensors:
• T2: One sensor is already mounted in the valve unit.
• T1: The second sensor must be mounted at the installation site ahead of the consumer
(valve in the return line; recommended) or after the consumer (valve in the supply line). The
immersion sleeve required is supplied already screwed onto the temperature sensor and must
be unscrewed for this for installation. The temperature sensor is already wired with the valve.
Note
!
• The cable between valve unit and
temperature sensor may not be either shortened
or lengthened.

Depending on the construction, temperature spread, medium and hydraulic circuit, the power
Q is not proportional to the volumetric flow of the water  (curve 1). With the classical type of
temperature control, an attempt is made to maintain the control signal Y proportional to the
power Q (curve 2) and is achieved by means of an equal-percentage valve characteristic curve
(curve 3).

The specially configured control parameters in connection with the precise velocity sensor
– ensure a stable quality of control. They are however not suitable for rapid control processes,
i.e. for domestic water control.
U5 displays the measured volumetric flow as voltage (factory setting).
It is always in reference to the respective nom, i.e. if max is e.g. 50% of nom, then Y = 10 V,

nom Is the maximum possible flow rate and corresponds to approximately 2 to 2.4 m/s medium
velocity in the connection pipes with the same DN size.
(For DN 65, the cross-section is approximately 0.065 m2 x Pi /4 = 0.0033 m2 and for
2.4 m/s medium velocity, this results in 480 L/min or 28.8 m3/h)
max Is the maximum flow rate which has been set with the greatest positioning signal, e.g. 10 V.
max can be set to between 45% and 100% of nom.
min 0% (non-variable).
Y [V]
Creep flow suppression
Flow rate [m3/h]
The medium velocity is <0.06 m/s in the opening point and can no longer be measured by the
sensor within a reasonable tolerance. This range is overridden electronically.
Opening valve The valve remains closed until the volumetric flow required by the positioning
signal Y corresponds to 2.5% of max. The control along the valve characteristic
curve is active after this value has been exceeded.
Closing valve The control along the valve characteristic curve is active up to the required
flow rate of 2.5% of nom. Once the level falls below this value, the flow rate is
maintained at 2.5% of nom. If the level falls below the flow rate of 0.5% of nom
required by the reference variable Y, then the valve will close.
